The raid on Greater Western Sydney's midfield stocks might not be over.

After Dylan Shiel nominated Essendon as his preferred destination, Hawthorn has been tipped to target Tom Scully.

There have been no public comments from Scully's camp or the Giants about his future, but his name keeps being raised in the media and former St Kilda champion Leigh Montagna believes the Hawks could make a move.

"It does feel if he does leave it would be to come back to Melbourne," Montagna said.

"St Kilda would love for him to go there, he'd be a great fit with his leadership and his running ability.

"Smells to me like a club like Hawthorn, they're someone who could land a Tom Scully ... keep a watch on Hawthorn."

The trades had a knock-on effect, advancing negotiations on several fronts. The Swans, who featured in the three-club deal that sent McGovern to Carlton then essentially swapped Rohan for Clarke, are now in a better position to finalise a trade for Hannebery.

Hannebery, who has three years to run on his current contract, is fully expected to become a Saint soon.

"We would like to think it's close to being done," Swans football manager Tom Harley said on AFL Trade Radio.

"The list managers sat down this afternoon. We would expect something to be done shortly." The Saints have also been freed-up to invest more time in Hannebery talks.

"It's exciting to not be frightened of the flight over to Perth to face Nic Nat," Hickey joked. "It almost seems a bit too good to be true, to be able to come and play for the reigning premiers."

Melbourne's Dom Tyson is expected to join North soon but the Demons have locked away midfielder Aaron vandenBerg, who considered a shift to Sydney before signing a contract extension that runs until the end of the 2021 season.

A deal between Essendon and the Giants regarding Shiel, who has a year to run on his current contract, will require plenty of brokering.

Port had little interest in posturing regarding Polec. They parted with the midfielder, Pittard and pick No. 48 in exchange for North Melbourne's pick No. 11 and a future fourth-round selection.
